高纬度候鸟的繁殖涉及迁徙、繁殖和换羽等功能之间的时间和能量分配问题。事实上，在一些物种中，特别是燕子和捕蝇草，进化的时间系统将婚后蜕皮完全或主要推迟到向南迁移之后（约翰逊1963）。在某些种群或物种中，如白纹带毛藻（Zonotrichia leucophrys gambelii）（Farner 1964），这三种功能在春末的整个过程中在时间上被急剧划分，
Breeding of migratory birds at high latitudes involves problems of allocation of time and energy among the functions of migration, reproduction itself, and molt. Indeed, in some species, notably swallows and flycatchers, the timing system that has evolved defers the postnuptial molt entirely or mainly until after the southward migration (Johnson 1963). In some populations or species, as in Zonotrichia leucophrys gambelii (Farner 1964), these three functions are sharply partitioned temporally through the course of the late spring and
